Title: Vacuum cleaner
Inventor: FUJIWARA TOSHIAKI
IPC: A47L9/02
Filed: 1990-05-31
Abstract: PURPOSE:To improve the durability of a switch by delaying the operation of a fan motor after a switch is turned on by a fan motor control portion. CONSTITUTION:A fan motor control portion 16 drives a bidirectional thyristor 22 through a resistance 23 by a transistor 24. The operating voltage of the transistor 24 is supplied from a d.c. power supply portion 21, and the voltage waveform of the d.c. power supply portion 21 is such that the time delay t1 is generated after a switch 19 is turned on, so that the drive of a fan motor 17 is delayed by the time t1. On the other hand, as a lamp 18 is directly driven by a switch 19, the rush current of the fan motor 17 flows in the switch 19 in the lapse of time t1 after the rush current of the lamp 18 flows therein so as to lessen the rush current just after the switch 19 is turned on. Thus, the durability of the switch 19 can be improved.

Filed: 1978-11-20
Abstract: PURPOSE:To make abonormality and normality checking of detectors easy and accurate by changing the voice states of a speaker according to the operation and non-operation of the assigned detector. CONSTITUTION:When one of the detectors 5-1-5-n to be checked is assigned by a switch C and ten keys 1, a display device 4 displays operation-check start and a display device 2 detector number respectively. In this state, the assigned detector is artificially repeated by repetition or the like of insertion and removal of an object into and from between a light projector and a photo detector in the case of, e.g., photoelectric switches. The change in the output signal by this is checked, and high tone oscillation sound pulses are generated from a speaker 3 when it is detected that the assigned detector has changed from OFF to ON and low tone oscillation sound pulses when it has changed from ON to OFF, respectively. Thereby, the operation checking of the detector may be readily and accurately performed.

Filed: 1989-06-08
Abstract: PURPOSE:To improve the general usefulness of an arithmetic circuit and to simplify the circuit constitution by selectively giving one of input data to the address input of an arithmetic table and referring to data stored in the address to obtain arithmetic results. CONSTITUTION:Picture element data a1 to 1i are inputted to a multiplexer 10, and one of these data is selectively given to an address input A 21 of an arithmetic table 20.
